I have read of a number of sofas being replaced with better recliners.
Don't worry about what others are doing, if it suits your family that is all that matters.
Go (all of you) and sit in it for an hour or two. Pretend to fix a meal. Pretend to get the kids bathed and ready for bed when the weather is too bad to go to the shower house. Where are you going to store the games and books? The dog's food? Where is each person going to sit to watch TV (not the tow vehicle)?
If you can survive while all inside, then it just gets easier when outside is available!
